Quantitative source apportionment of heavy metals in atmospheric deposition of a typical heavily polluted city in Northern China: Comparison of PMF and UNMIX

open access: yesFrontiers in Environmental Science, 2022
Receptor models are rarely utilized in atmospheric deposition but are often used to identify pollutant sources and quantify their contributions. This article focuses on the soil in atmospheric deposition in a typical polluted city. Atmospheric deposition

Fluxes, patterns and sources of phosphorus deposition in an urban–rural transition region in Southwest China [PDF]

open access: yesAtmospheric Chemistry and Physics, 2022
Understanding the patterns of atmospheric phosphorus (P) deposition is essential for assessing the global P biogeochemical cycle. Atmospheric P is an essential source of P in agricultural activities as well as eutrophication in waters; however, the ...

Dry Deposition of Atmospheric Aerosols: Approaches, Observations, and Mechanisms.

open access: yesAnnual review of physical chemistry (Print), 2021
Aerosols are liquid or solid particles suspended in the atmosphere, typically with diameters on the order of nanometers to microns. These particles impact air quality and the radiative balance of the planet.

Corrosion of steel reinforced concrete in the tropical coastal atmosphere of Havana City, Cuba

open access: yesQuímica Nova, 2013
The influence of chloride deposition rate on concrete using an atmospheric corrosion approach is rarely studied in the literature. Seven exposure sites were selected in Havana City, Cuba, for exposure of reinforced concrete samples.

Nitrogen deposition and multi-dimensional plant diversity at the landscape scale [PDF]

open access: yesRoyal Society Open Science, 2015
Estimating effects of nitrogen (N) deposition is essential for understanding human impacts on biodiversity. However, studies relating atmospheric N deposition to plant diversity are usually restricted to small plots of high conservation value.

Linking atmospheric emission and deposition to accumulation of soil cadmium in the Middle-Lower Yangtze Plain, China

open access: yesJournal of Integrative Agriculture, 2023
Cadmium (Cd) is one of the most toxic heavy metals in the environment. Atmospheric deposition has been found to be the main source of Cd pollution of soil on a large scale in China, and identification of the relationships between anthropogenic emission ...

Changes in dissolved iron deposition to the oceans driven by human activity: a 3-D global modelling study [PDF]

open access: yes, 2015
The global atmospheric iron (Fe) cycle is parameterized in the global 3-D chemical transport model TM4-ECPL to simulate the proton- and the organic ligand-promoted mineral-Fe dissolution as well as the aqueous-phase photochemical reactions between the ...
